Smart Ingredient Swaps and Customization Tips

If you’re looking to tailor these cookie bars to different dietary needs or simply work with what you have in your pantry, here are some smart swaps:

• Cake Mix Alternative: Use a homemade blend of flour, sugar, baking powder, and salt if you’re out of cake mix
• Butter Substitute: Coconut oil or vegan butter works great for a dairy-free version
• Egg Replacement: Try flax eggs (1 tbsp flaxseed + 3 tbsp water per egg) for an egg-free variation
• Candy Swap: Use M&M’s, peanut butter chips, or chopped peanut butter cups in place of Reese’s Pieces for a twist

How to Make Reese’s Pieces Chocolate Chip Cookie Bars – Step by Step

1. Preheat the Oven
   Set your oven to 350°F (175°C) so it’s ready by the time your batter is mixed. Grease a 9×13-inch baking pan or line it with parchment paper for easy cleanup.
2. Mix the Dough
   In a large mixing bowl, combine the yellow cake mix, melted butter, vanilla extract, and eggs. Stir until the mixture forms a thick, uniform batter.
3. Add the Chocolate Chips
   Fold in the chocolate chips gently, ensuring they’re evenly spread throughout the batter for consistent flavor in each bite.
4. Press Into the Pan
   Using a spatula or clean hands, press the dough evenly into the prepared baking pan. Take care to get into the corners and create a level surface.
5. Top with Reese’s Pieces
   Sprinkle Reese’s Pieces over the top of the dough. Gently press them in so they stick while baking.
6. Bake to Perfection
   Bake in the preheated oven for 20–25 minutes. The edges should be golden brown and the center just set—not jiggly. Don’t overbake to keep the bars soft and chewy.
7. Cool and Slice
   Let the bars cool completely in the pan before slicing into 16 even squares or rectangles. This helps the bars hold their shape and makes cutting cleaner.

Pro Tips to Get the Best Cookie Bars Every Time

To take your Reese’s Pieces Chocolate Chip Cookie Bars from good to great, keep these pro tips in mind:

• Room Temp Ingredients: Using room temperature eggs helps them mix more easily into the batter
• Parchment Lining: Makes removing the bars from the pan mess-free and simple
